Design of tripping capacity detection device for release of low voltage DC circuit breaker
Starting from the principle of tripping electromagnetic conversion of electromagnetic trippers with mature application technology on the market, this paper designs a kind of electromagnetic tripping ability detection device for low-voltage DC circuit breaker by using the advantages of SS495A linear Hall effect sensor, and proposes specific detection methods. Through the analog Hall sensor unit to collect the electromagnetic suction of the low-voltage DC circuit breaker tripper tripper tripper, the output voltage analog signal is transmitted to the signal detection processing unit through the operation amplification circuit and the analog signal processed by the amplification circuit enters the microprocessor to judge the detection results, and the tripper operation is obtained whether the tripper is correct or not. The design of this device can solve the problem of detecting the tripper at any time without disassembling the circuit breaker device, which not only ensures the reliability of power supply but also greatly improves the detection efficiency.
